Alignment today shows up a front end repair. Upper Control Arm?

[willrev]

Got my 82 300sd aligned at the dealer for the first time. It was $99.

Got in the car to go home and heard creaking in steering on front end. Went back to dealer. Very nice mechanic came back out and showed me what was going on.

The passenger side upper control arm jumped up and down when the wheel is turned. Can I lubricate somehow till I can get it fixed? He said an hour and half labor of $135. Can I do this repair myself or are there special tools?

He also said the creaking when stopping was the brake strut support joint on that same side. This is also the caster adjustment. He reccomended doing both sides of these at the same time since an alignment would be necessary

Any opinions?
